Abstract: IMPROVED TUBE CUTTING APPARATUS          ABSTRACT A ram driven tube cutting apparatus of the double cut type in which sections of tubing are suc-cessively severed from a continuous length thereof by a notching cut followed by a severing cut, includes improved mechanism for clamping the tubing during the cutting process.  A pair of opposed, complemental die jaws are mounted on slides controlled by spaced cam followers carried by the slides.  A reciprocating wedge cam engages and forces the cam followers apart to move the slides thereby closing the jaws on the tubing.  One of the cam followers comprises a roller mounted on an eccentric shaft which may be selectively rotated to adjust the clearance between the die jaws. The other cam follower is spring loaded toward the cam within a slide mounting provided in its slide and automatically shifts to an overload position to avoid damage to the mechanism when foreign objects become lodged between the die jaws.  Each of the die jaws consists of a pair of die jaw portions having spaced, opposed forces defining a slot through which  a severing blade may pass.  The die jaw portions are removably mounted on the slides by bolts anchored with trap nuts slidably confined within a T-shaped passageway  in the slides to permit adjustment of the spacing between opposed  faces of the die jaw portions.

Abstract: ABSTRACT OF THE DISCLOSURE     A transducer for generating a feedback signal representative of the position of a movable member includes a signal generating mechanism for providing an electrical feedback signal representative of the position of the movable member.  The signal generating mechanism includes a first shaft portion having a first longitudinal centerline and a drive mechanism having a shaft member coupled in driving engagement to the first shaft portion.  The drive mechanism is adapted to be cable connected to one of a plurality of movable members having maximum travel spans different one from the other.  The shaft member has a shaft longitudinal centerline which is concentric with the first centerline, the centerlines defining a first axis.  An alignment mechanism is coupled to the drive mechanism and the signal generating mechanism and permits limited movement of the first axis with respect to a reference axis.  The alignment mechanism thereby isolates the signal generating mechanism from misalignment reaction forces.

Abstract: ABSTRACT OF THE DISCLOSURE           A folding row marker for an agricultural implement includes a marker arm having two separate sections pivoted in the middle, the sections being extended and aligned in an unfolded or use position and being foldable to a storage position and being actuated between the use and storage position by an hydraulic cylinder.  A swing link which is pivotally mounted to the frame of the implement guides the rod end of the cylinder about its pivotal connection to the frame, and a push/pull link connected to the swing link and pivotally connected to the base of the marker arm is generally aligned with the axis of the cylinder when the cylinder is retracted and pushes the base of the marker arm about its pivotal connection to the frame.  During initial extension motion of the cylinder, equal increments of elongation of the cylinder cause generally equal angular dis-placement or rotation of the marker arm as it is moved to the use position.  As the marker arm is moved toward the storage position and passes over top dead center, the push/pull link is placed in tension, holding the marker arm against its weight.          As the marker arm approaches the storage position, the push/pull link is rotated to a position such that equal increments of extension of the cylinder caused progressively smaller increments of angular displacement of the marker arm, thereby causing the marker arm to decelerate as the cylinder reaches the end of an extension sequence.

Abstract: ABSTRACT            The value of a transverse moment of any order of the electromagnetic field associated with an optical beam (and in particular the spot size of such a beam) is deter-mined by two successive measurements of the optical power of the beam:  one measurement is a direct measurement, whilst the other is effected after spatially modulating the transverse distribution of the electromagnetic field by a factor proportional to the n-th power of the trans-verse coordinate of the beam, n being the moment order. The moment can be obtained from the ratio between the two measurements.  The invention also includes apparatus for carrying out the method.

Abstract: "PROCESS FOR REMOVAL OF HYDROGEN SULFIDE   AND CARBON DIOXIDE FROM GAS STREAMS"                                   ABSTRACT     A gas treating process is disclosed.  Hydrogen sulfide and carbon dioxide are removed from a hydrocarbon vapor stream by absorp-tion into an aqueous carbonate solution.  Hydrogen sulfide picked up by the circulating carbonate solution is oxidized to produce liquid sulfur, which is withdrawn.  The carbonate solution is then stripped to release carbon dioxide and produce the lean carbonate solution used for absorption.  By-product thiosulfate formed in the oxidation step is eliminated by reaction with hydrogen sulfide.  Metal phthalo-cyanines are used as the catalyst for the elimination of thiosulfate and for the oxidation of hydrogen sulfide.
